IMPROVEMENT IN GANG-PLoWs.l

The Schedule referrec to in these Letters Patent and making part of the same.

T o all whom, it may concer-n Be it known that I, J AcoB PRICE, of San Leandro, in the county of Alameda and State of California, have invented a new and useful Improvement in Gang- Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make` and use the same, reference being had to the accompanying draw ings forming part of this specifica-tion, in which- Figure 1 is a top view of my improved gang-plow.

Figure 2 isa side vie-w of the same partly in section, through theline x x, fig. l.

Figure 3 is a detail view of a part of the same.

Similar letters of reference indicate corresponding parts.

My invention has forl its object to furnish an improved gang-plow, which shall be so constructed and arranged that the driver can raise the plows from the \ground without having to raise himself at the same time; and

It consists in the construction and combination of the various parts, by means of which these adjustments areeected, as hereinaftermore fully described.'

A are the plows, the standards of which are sccurely attached'to the rear parts of the beams B.

The 4rear parts of the beams B are connected and held in their proper relative positions by a cross-bar b, as shown in g. 1.

The Vforward ends of the beams B are securely bolted to the rear end of thetongue C, which is thus rigidly connected with the said plow-beams.

D1 D2 is the axle, which is made in two parts, and upon the journals of which the wheels E revolve in the ordinary manner.

F are tWo bent levers made in about the form shown in g. 2, and the forward ends of which are connected and held in their proper relative positions by the footboard G. l

The levers F have holes formed in v them for the passage of the longer part D1 of the axle, which axle thus becomes the fulcrum of said levers.

The rear ends of the levers F are connected to each other, and at the same time pivoted to the rear parts of the'beams B, by being attached to the ends of a long bolt which is connected with the said beams by eye-bolts or staples, as shown in figs. 1 and 2.

H is the drivers seat, which Iis attached to and supported by the standards I, the lower ends of which are made branched, and are securely riveted or bolted to the front and rear arms of the levers'F, as shown in iig. 2.

J isa bar, the lower end of which is securely at tached to'the tongue O, and which has notches formed in its side edge, as shown in fig. 3.

The rack-bar J passes up through a hole in the foot-board G, and its upper end is securely attached to or formed solid. with the brace-bar K.

The lower end of' the brace-bar K is securely attached to the tongueC, and upon its upper end is formed a loop or. handle for the driver to take hohl of when raising the plows from the ground.

L is abent lever, which is pivoted to the foot-board G in such a position that the catch formed upon the upper arm ot said lever may enter-the notches in the rack-bar J, and hold the: plows securely in the position to which they may have been raised.

Beneath the end of the other arm ofthe lever-catch L, which extends along the upper side oi' the footboard G, isplaced a spring, M, which holds the said arm raised to hold the catch oi' said lever forward against the rack-bar J, until withdrawn by the driver by placing his foot upon the said horizontal arm of the. said lever-catch L.

Upon the inner end of the part Dl of the axle is formed, or to it is attached anarm, d', which is made in about the form and manner shown in iig. 3, and the vertical part of which passes through a socket, d2, formed in or attached to the. inner -end of the 'part Di of the axle.

The upper end of the arm l1 is bent inward, and enters a hole in the bar N, the upper end of which -is riveted or bolted to the standard I, and the lower end of which is notched to iit and ride upon the part 'DI of the axle.

The bar N, supports the upper end of the arm d* against the dratt strain.

The socket cl2 is made larger than the body of the arm d* upon which it is placed, and is secured in place, when adjusted at the desired height, by a wedge, O, driven into the said socket upon the outer side of the said arm dl, as shown in iig. 3.

This'construction enables the height of the near wheeLE to be raised or lowered as the depth of' the furrows may require.

` When the plows are to be raised, the driver places his foot upon the horizontal arm of the lever L, and thus removes the catch of said lever from the rackbar J.

He then throws his weight upon the foot-board G, which raises the rear ends of the beams B and also the plows connected with4 said beams.

Ii' desired or necessary, the driver may increase the eiect of his weight by pulling upon the handle of the bars J K.

To lower the plows, the driver withdraws the spring lever-catch L from the rack .I with his foot, which allows the plows to drop to the desired depth.'

Havn g thus described my invention,

I claim as new and desire to secure by Letters Patent- 1; The levers F, constructed as described, and havherein shown anddescribed, and for the purposes set ing the foot-board G attached to their forward ends, forth. y in combination with the axle Dl D2, and plow-beams Theabovespeciieation of my invention signed by B, substantially as herein shown and described, and me this 26th day of October, 1869. for the purpose set forth. 4 JACOB PRICE.
